Camera locations

ELOC_REAR     // The camera is on the backside of the device, the common location for recording. 
ELOC_FRONT    // The camera is on the screen side of the device, the common location for video calls. 
ELOC_UNKNOWN  // The position is unknown or can be changed.  

The camera locations are currently provided on most Series 60 devices, and on some Windows Mobile devices.

Flags for camera image orientation relative to the screen. You can use this to rotate the camera into its correct position.

EDSP_YVU12    // Y plane followed by a V plane and a U plane at half dimensions
